AUGUSTINE F. LITTLEFIELD, OF LYNN, MASSACHUSETTS.

INNER SOLE.

SPECIFICATION forming part of Letters Patent No. 462,442, dated November 3, 1891.

Application led February 12, 1891. Serial No. 381.189. (No model.)

To all whom it 11mg concern.-

lie it known that l, AUGUSTINE F. LITTLE- EIELD, of Lynn, in the countv of Essex and Slate of Massachusetts, have invented a new' and Improved Inner Sole, of which the following is a full, clear, and exact description.

My invention relates to improvements in that class of inner soles which are used in the manufacture of hand-sewed boots and shoes; and the object of my invention is to produce an inner sole which will be light and fiexible, but-which will have the necessarystrength, and which may be formed from lighter stock than the inner soles in ordinary use.

'lo this end my invention consists in an inner sole having a channel molded or pressed therein and a suitable strengthening 1nate rial adapt-ed to be insert-ed in the channel.

This construction will be hereinafter fully described, and specifically pointed outin the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters ot' reference indicate corresponding parts in all the figures.

Figure l is a broken plan view of an inner sole embodying my invention. Fig. 2 is a vertical longitudinal section of the same on the. line' 2 of Fig. l. Fig. 3 is an vinverted plan of the inner sole, and Fig. 4 is a transverse section on the'line l 4 of Fig. l.

lt is well known that in hand-sewed work the inner soles are usually provided with a channel, which is cut therein near the edge of tbe sole and which adapts the innersole for attachment to the shoe-upper, and in forming an inner sole in this manner it is necessary that the stock should have sufficient thickness for a channel to be cut therein;

but by molding or pressing a channel in the inner sole very much lighter stock may be used.

lhe inner sole A is provided with a channel a, which extends around the inner sole, near thc edge thereof, in the usual manner;

but instead of being cut therein the channel is pressed in the inner sole, the inner sole be ing placed in a suitable mold for the purpose and the channel being formed so as to project from the lower surface of theinner sole. 'lo give additional strength tothe channel u it may be provided with a filling b, of leather, rubber, or of any suitable material, and said filling may be glued, stitched, or otherwise fastened in the channel. 'lhe inner sole is provided with the usual heel-piece A to give the necessary .thickness to the heel portion, and with the veneer or lining B, which ma)r be pasted or stitched thereto, and when the veneer is stitched to the inner sole the thread Inay be passed through the ven eer and th ron gh the filling b, ,thus confining the veneer and filling at one operation.

The veneer B is doubled over the edge of the inner sole, as shown in b in Figs. 3 and 4, and extends inward on the inner-sole bof-4 tom, so as to eoverthe channel, and it serves to strengthen the inner sole, and if made of suitable material renders the inner-sole water-proof.

The inner sole is applied to the shoe in the usual manner, and as the application is so well understood by the trade it'has not been shown in the accompanying drawings. The inner sole may be used either with or without the filling b; butlit will be found desirable in most cases to use the filling.
